What to Consider When Buying Battery Powered Backpack Sprayer

You can find many sprayers in the market today, and each has varying features and quality to offer. These aspects will greatly affect how a sprayer will perform, so it’s essential to consider them before deciding.

Use and Purpose of Sprayer

First and foremost, it’s essential to determine why you are buying a battery-powered backpack sprayer. If you know the job at hand and what it requires from a sprayer, you’ll easily spot the unit that can fulfill what needs to get done. For instance, if you need to constantly spray in a larger yard, you’ll need an extra-durable sprayer designed for heavy-duty spraying tasks. The chemicals you use will also affect the kind of sprayer you should be buying. If you are mainly dealing with oil-based chemicals, the best battery powered backpack sprayer for the job should have oil-resistant seals to prevent any leaking issues.

Pump Type

The pump of a backpack sprayer is one of its essential components. You shouldn’t settle for a sprayer model without checking this feature first as pumps come in varying sizes and shapes, and they have their pros and cons. 

Two primary choices you have for pump types in sprayers are: 

  • Diaphragm Pump – This pump type can typically dish out liquid between 40 to 60 psi, which are in the lower pressure range for backpack sprayers. However, a diaphragm pump can handle a wide range of chemicals and products, offering a sprayer’s versatility. While it might not be the best option for spraying in larger farmlands, a sprayer with a diaphragm pump is what you want to get for home and commercial purposes.
  • Piston Pump – A piston pump is a fantastic choice for looking for the best battery powered backpack sprayer that can produce high spraying pressure or up to 150 psi. The only downside is they can only handle a select type of chemical or product. It won’t be the best choice if you’re planning to use wettable powders in your yard. However, a sprayer with a piston pump is ideal for larger plots and farms for quicker spraying sessions.


A special sealant is essential for a backpack sprayer, especially since you will handle harsh chemicals and material. What you want to look for in a sprayer sealant feature is a Viton seal. It’s the kind that offers excellent chemical resistance, making your sprayer suitable for use even with corrosive products. Most of the high-end and top-quality backpack sprayers will use Viton seals for the construction.

Spray Wand and Nozzles

The spray wand is what puts a distance between you and the chemicals you’re spraying. Ideally, you want it to be long enough that it’s not spraying on you but still easy to handle and maneuver. 

Meanwhile, the spray nozzle at the end of the wand controls the spray pattern and flow rate. Most backpack sprayers will come with a couple of different nozzle adjustments that vary in their spread. Common spray patterns for nozzles are direct, fan, cone, and wide stream. If your unit comes with these attachments for free, it’s a fantastic bonus as it gives you control over your spraying performance. 

Battery Life

For the best battery powered backpack sprayer, battery life or runtime is essential. It determines how long the sprayer is usable in between charges. Some units have long-lasting batteries that provide power for non-stop spraying for up to ten hours or more. They will be ideal to have if you need to cover larger plots of land. Meanwhile, some models can only handle a couple of hours of continuous spraying, which are cheaper but only suitable for lightweight spraying tasks for smaller areas.

Sprayer Tank Capacity

Sprayers are usually available with a 2-gallon to 7-gallon capacity. The smallest capacity unit usually only comes with a handle, which you can easily carry around. Meanwhile, large-capacity tanks may be too heavy to carry on your back. Ideally, the best battery powered backpack sprayer should be light enough to carry on your back but still has a significant tank capacity to offer. 

Today, most backpack sprayers feature a 4-gallon tank, which is enough for most uses, like covering an area between 5,000 to 10,000 square feet.


The spraying pressure that a backpack sprayer can dish out greatly varies from one model to another. The key to finding the best battery powered backpack sprayer in terms of pressure is to find one that matches your intended application. 

A sprayer that can produce 40 to 60 psi is suitable for most spraying applications. They can usually cover 15 to 20 feet of horizontal distance. Meanwhile, if you want better coverage for a quicker spraying session in large farmlands, you might want to consider getting a sprayer that can dish out liquid up to 150 psi. 

Many sprayer models will also feature dual pressure, allowing you to switch between low to high pressure as necessary for the job. This type of sprayer will include a knob that you can simply form to switch between pressures.

Chemical Rating

Chemicals used in farms, lawns, and gardens can be pretty intense. Most herbicides and pesticides are corrosive, so it’s important to ensure that your sprayer comes designed to handle whatever liquid you’re going to use. Checking for correct chemical rating doesn’t only include the sprayer tank, but also other parts and accessories like the hoes, sprayer wand, seals, and other accessories. 

Straps and Lumbar Support

Even a lightweight backpack sprayer can get heavy when you fill the tank. Ideally, you want something with straps that won’t eat to your shoulders. Check out for models with wide shoulder straps and thick and comfortable padded design for maximum comfort. A backpack sprayer with a waist strap will also help keep the unit in place while you’re working.

Durability and Ease of Repair

Durability is one of the critical factors to consider when buying outdoor equipment like a backpack sprayer. The easiest way to determine if a sprayer is durable enough to handle outdoor tasks is to look for its material. High-density polyethylene material is the best choice for sprayers. It’s a tough kid that can handle daily wear and tear in the job. 

However, you might also want to consider getting a sprayer that features a UV protection coating for extra durability. Plastic can easily deteriorate under extreme outdoor conditions like UV radiation, and an extra coating ensures that your sprayer will last longer. 

Also, check the seals, hoses, and other accessories of the sprayer. Ensure that they come with a rating ideal for herbicides or additives you’re going to use. If these parts are easily available in your local suppliers or online, it’s more convenient for you to make repairs when necessary.


Getting the best battery powered backpack sprayer can save you time and effort in making sure that your land gets good maintenance and care. It’s a handy tool when applying herbicides or pesticides in farms and lots. Our best pick for the job is Chapin International for its spraying quality and performance. It’s a fantastic option without breaking your savings. 

Still, you should choose the best battery powered backpack sprayer according to your spraying needs and preferences. It includes selecting the best unit with the ideal spraying pressure, tank capacity, durability, and chemical rating for your intended purpose.

FAQs (Frequently Asked Questions)

How much pressure should my sprayer have?

It depends on your intended purpose or your application. A sprayer with 40 to 60 psi spraying pressure is ideal for most purposes. However, if you are looking for a unit that can sprayer wider areas in a short period, a model with a 100 to 150 psi pressure rating will get the job done faster. 

How long is the reach of a garden sprayer?

It depends on things, the length of the sprayer wand, and the spraying pressure. Usually, a standard sprayer with 40 to 60 psi spraying pressure has a spraying distance of 15 to 20 feet.
